Abstract

Effects of protease, $CaCl_2$ EGTA, polybrene, medium pH, and formaldehyde on the infection and inactivation of human rotavirus Wa were investigated using T-flask culture of monkey kidney MA-104 cells. Rotavirus titer was improved by the addition of trypsin or clostripain. Rotavirus titer was increaeed 8 and 10 time sin the infection medium supplemented with 300 $\mu\textrm{g}$/mL of $CaCl_2$ and in the medium adjusted its pH to 8, respectively. However, addition of EGTA or polybrene to the medium decreased rotavirus titer. Rotavirus titer was reduced to 53-95% of the initial value at 1 hr after formaldehyde treatment. Furthermore, rotavirus was inactivated more than 98% at 12 hrs after formaldehyde treatment.

원숭이 콩팥세포를 T-flask에서 배양할 때 로타바이러스 감염에 미치는 protease, $CaCl_2$. EGTA, po]ybrene 감염배지내에서 pH의 영향과 formaldehyde에 의한 로타바이러스의 inactivation 정도를 조사하였다. 로타바이러스의 증식은 trypsin이나 clostripain과 같은 protease의 첨가에 의해 크게 향상되었다. $CaCl_2$ 농도가 300 mg/ml이거나 pH가 8인 감염배지에서 로타바이러스의 증식은 각각 8 및 10 배 증가하였다 그러나 EGTA 와 polybrene을 감염배지에 첨가하였을 때 바이러스 증식은 감소하였다. Fonnaldehyde는 로타바이러스 inactivation에 유효하였으며 로타바이러스의 농도는 fomrmaldehyde를 처리하였을 때 1 시간 후 약 53-95% 수준으로 감소하였으며 12 시간 후에는 로타바이러스가 98% 이상 inactivation 되었다.
